java - Tomcat 在 webapp 启动期间挂起

Question

我的web 项目 运行良好，它包括:spring3 和hibernate3。借助eclipse 重构 对eclipse 中的一些字段进行重命名后，tomcat 无法启动。它卡在下面的这些日志上:

奇怪的地方没有错误!Spring有任何错误吗？为什么它不告诉扫描或任何其他过程是否有问题，我无法理解。 Eclipse 一切正常，Tomcat 却挂了，真是荒唐!

Answer 1

要解决您的问题，请执行以下步骤:

1. 查看 eclipse 重构时生成的脚本并比较字段中的变化。
2. 进入 xml 配置文件:spring、hibernate、castor、web,...等并查看比较的字段是否不变或过度更改并替换为更改

如果上述步骤对执行这些步骤没有帮助:

1. 从您的存储库下载您的项目的新版本，并确保运行以查看是否一切正常
2. 从您的更改中一次执行一个相同的更改脚本，每次运行你的项目，看是否正常运行
3. 当您的项目停止工作时，您会知道concrete field-change tomcat 开始挂了，深入了解一下铲球
